[Fixed]-Django crispy-forms disable browser's 'Save Password' popup

If you are using a FormHelper, you can set attrs (docs).

For example to set autocomplete="off" as in the answer you linked to, you would do:

class ExampleForm(forms.Form):
    def __init__(self, *args, **kwargs):
        super(ExampleForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.attrs = {'autocomplete': 'off'}
